Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heated cigarettes, in particular to an aerosol generating article with humidity indication and adjustable resistance. BACKGROUND

[0002] The heated smoking set on the market can produce low-temperature smoke by heating a cigarette, and when in use, the cigarette is inserted into a heating chamber, and the heating body is heated by power supply to heat the cigarette. Whether the heating body is centrally heated or peripherally heated, the heating temperature is usually between 180℃ and 300℃. Since a large amount of glycerol or propylene glycol with hygroscopicity is contained in the heated cigarette, the product will gradually absorb the moisture in the air after leaving the factory, and the absorbed moisture will evaporate and be brought into the consumer's mouth during the first puff, sometimes reaching about 70-80 degrees, which brings an uncomfortable feeling of burning mouth to the smoker. At present, although some people have proposed to reduce the temperature of smoke by increasing the ventilation port and adding a cooling section, but for the cigarettes with short time since leaving the factory and not yet absorbing moisture, this method will affect the taste of the product and reduce the richness.

[0003] Therefore, how to reduce the temperature of smoke only when necessary and improve the quality of smoke suction has important significance. SUMMARY

DETAILED DESCRIPTION

[0048] The detailed description set forth below in connection with the appended drawings describes exemplary features and the best mode contemplated at present for carrying out the patent. It is to be understood that the description is merely exemplary of the principles of the patent, and that modifications of the principles as set forth in the description are within the scope of the patent. Accordingly, the patent is not intended to be limited to the examples described herein but rather is to be accorded the widest scope consistent with the principles and novel features disclosed herein and defined by the following claims, along with their equivalents.

[0049] It is to be understood that the same may be employed in other embodiments and that not all of the described features need necessarily be employed. It is also to be understood that, in this description, similar reference numerals and letters in the various figures and embodiments refer to similar items, and that, as such, once named, similar items are not necessarily re-introduced in every figure and embodiment in which they appear.

[0050] In order to make the purposes, technical solutions and advantages of the patent clearer, the embodiments of the patent will be further described in detail below with reference to the drawings.

[0051] According to the consumer's usage habits, the direction close to the consumer's mouth during suction is referred to as the proximal end in this article, and conversely, the direction away from the consumer's mouth is referred to as the distal end in this article.

[0052] like Figure 1 As shown, the aerosol-generating article 100 typically takes the form of a cigarette, comprising a blocking section 150 extending from the distal end to the proximal end, an aerosol-generating substrate 110, a first hollow portion 120, a second hollow portion 130, and a filter portion 140 at the mouth end. The aerosol-generating substrate 110 is primarily composed of tobacco or reconstituted tobacco and can be referred to as the tobacco segment. The first hollow portion 120, the second hollow portion 130, and the filter portion 140 at the mouth end can be collectively referred to as a filter rod segment. These components can be secured and / or connected by specific layers within the wrapping layer. For example, the aerosol-generating substrate can be wrapped with cigarette paper, and the filter rod segment components can be wrapped with plug wrap, which can also be connected to each other using tipping paper.

[0053] like Figure 2 As shown, the blocking section 150 includes a first blocking member 151 at the distal end and a second blocking member 152 at the proximal end of the first blocking member 151. The first and second blocking members are connected by a wrapping layer 170. The wrapping layer 170 has a weakening line 171 at the connection between the first and second blocking members 151, so that the first blocking member 151 can be easily removed by the consumer without damaging other structures of the cigarette.

[0054] The first blocking member 151 and the second blocking member 152 are respectively made of fiber tow material, corrugated metal sheet material, corrugated paper, porous ceramic, perforated silicone, or biomass firmware. The first blocking member and the second blocking member are made of such low-resistance materials to allow air to enter the tobacco segment 110 from the distal end of the aerosol-generating article.

[0055] The fiber tow material can be cellulose acetate, commonly used in traditional cigarettes. Cellulose acetate fibers are often sprayed with a glycerol acetate additive, which bonds to adjacent fibers and provides the desired hardness for the filter. The fiber tow material can also be polylactic acid, which is more biodegradable than cellulose acetate and can therefore be used to fully or partially replace cellulose acetate in filters.

[0056] The corrugated metal sheet can be aluminum foil, and the corrugated polymer sheet can be polylactic acid. The corrugated metal sheet can be textured using suitable known machinery for texturizing metal, polymer, or paper sheets. For example, the sheet used to form the plugging segment can be corrugated using a corrugating unit of the type described in CH691156A, comprising a pair of rotatable corrugating rollers. The textured sheet can be wrapped in forming paper like fiber tow and cut into cylindrical segments.

[0057] Porous materials such as porous metal foam, porous ceramic, porous graphite, etc. can be directly cut according to the required shape using various oil absorption materials commonly used in the field of electronic cigarettes. In addition, holes can be punched in silica gel to form enough pores to meet the required air permeability of the plugging member.

[0058] The biomass solid piece can be based on bamboo powder or plastic starch, with guar gum, sodium alginate, gelatin, etc. as the binder, with tobacco dust as the auxiliary flavoring material, and with a certain amount of glycerol as the plasticizer to improve the smoothness of the surface of the solid piece material. The raw materials are physically blended and extruded by a screw extruder to form a solid piece material of the required shape.

[0059] The filter rod segment includes a first hollow segment and a second hollow segment, for example, a first ventilation hole 161 and a second ventilation hole 162 can be provided at the first hollow segment, and the first ventilation hole 161 is located at the distal end relative to the second ventilation hole 162. In use, as shown in Figure 6 When the first plugging member 151 is not removed, both the first ventilation hole 161 and the second ventilation hole 162 are exposed outside the aerosol generating device after the aerosol generating article 100 is completely inserted into the aerosol generating device 200; as shown in Figure 7 When the first plugging member is removed, the first ventilation hole 161 is blocked by the aerosol generating device, and the second ventilation hole 162 is exposed outside the aerosol generating device after the aerosol generating article 100 is completely inserted into the aerosol generating device 200.

[0060] If the cigarette 100 satisfies the following formula, the disassembled cigarette 100 is more easily positioned in the appropriate position of the heating chamber 220, so that the first ventilation hole 161 is blocked by the smoking set while the second ventilation hole 162 is exposed outside the smoking set:

[0061] 0.8xH≤L≤1.1xH,

[0062] wherein L is the length of the first plugging member 151, and H is the distance between the first ventilation hole 161 and the second ventilation hole 162.

[0063] If the cigarette 100 satisfies, the disassembled cigarette 100 has the same total resistance after being inserted into the heating smoking set 200 as the original, and the consumer does not need to adapt to the change in suction caused by the resistance:

[0064] 0.8xPD1≤PD2≤1.2xPD1,

[0065] wherein PD1 is the resistance of the aerosol generating article 100, and PD2 is the resistance of the aerosol generating article 100 after the first plugging member 151 is removed and the first ventilation hole 161 is closed.

[0066] In one embodiment, the cigarette is provided with more ventilation holes. The ventilation holes can be round, square, triangular or other polygonal shapes, and can be formed by laser drilling, stamping, piercing, etc. Multiple groups of ventilation holes can be uniformly distributed in the length direction, one group of ventilation holes can be uniformly distributed in the circumferential direction, and two groups of ventilation holes can be staggered in the circumferential direction.

[0067] The cigarette or the cigarette case for packaging the cigarette has a humidity indicator, which can inform the consumer of information related to the current water content of the tobacco segment 110 of the cigarette.

[0068] In one embodiment: when the humidity of the tobacco segment is less than or equal to 20% RH, the color of the humidity indicator is different from the background, and the color is fully developed, so the consumer can easily notice this and will remove the first blocking piece with developed color, which can ensure the richness of the smoke. When the humidity of the tobacco segment is greater than or equal to 35% RH, the color of the humidity indicator is the same as the background, and the humidity indicator is completely colorless. When the humidity of the tobacco segment in the cigarette is too high, the first puff after heating is easy to be too hot, at this time, a larger amount of cooling air needs to be introduced, and the first blocking piece can be retained. For the case where the humidity indicator does not develop color, the consumer can heat directly without disassembling the cigarette.

[0069] In another embodiment: when the humidity of the tobacco segment is less than or equal to 20% RH, the color of the humidity indicator is different from the background, and the humidity indicator presents a pattern or text to prompt the consumer to remove the first blocking piece; when the humidity of the tobacco segment is greater than or equal to 35% RH, the color of the humidity indicator is the same as the background, and no pattern or text is presented.

[0070] In one embodiment, the humidity indicator is on the outer surface of the portion of the wrapping layer 170 surrounding the first blocking piece; in another embodiment, the humidity indicator is on the distal end of the first blocking piece.

[0071] In one embodiment, the humidity indicator is a paint that can be directly purchased on the market and applied to the cigarette, including a colorless dye, a color developing agent, and a desensitizer, which can temporarily prevent the color developing agent from acting, so that the colorless dye remains colorless or substantially colorless until the humidity reaches a certain level.
